More than 40 minutes passed before anyone at the Busch family mansion called to report the death of the 27-year-old girlfriend of former Anheuser-Busch CEO August Busch IV, the St. Louis Post-Dispatch reported Saturday.

Adrienne N. Martin was found dead Dec. 19 at the house, outside St. Louis, around 12:30pm local time. But emergency responders were not called until 1:12pm about an “unresponsive person,” according to police.

Paramedics arrived soon after and pronounced Martin dead at 1:26pm.

It is still unclear what time Martin died, but investigators were told she was last seen alive at 3:30am, according to police.

Art Margulis, a lawyer for Busch, said Busch was at the mansion when the death was discovered Sunday.

Martin, a former Hooters waitress and aspiring beer advertising model, and Busch had been dating for a year, according to reports. Margulis said there was “absolutely nothing suspicious about her passing, and it’s a tragic and untimely death of a young person.”

On Thursday, Thomas M. Becker, chief of police for the St. Louis suburb of Frontenac, declined to comment on a report in the St. Louis Post-Dispatch that the death was initially being investigated as a possible overdose.
